Definitions

This invention concerns the forming of a communication network.
a cellular network can be thousands of links in size, and there can be several technologies in the network.
the process of forming a network is very much an iterative process where many interrelated decisions must be made. Often the process hits a dead end. Usually manual work which is error-prone, is needed to set up parameters for each piece of equipment in the network. As a consequence, errors cause delays in the process under way. Sometimes penalties for missing the agreed deadlines have to be paid. Often the whole network is not formed at the same time but the network expands with time. To take care of the whole process for forming a cellular network is a difficult task. Attention must be paid to the expansion of the network. At present, there are many parallel arrangements to handle the process and expansion of a network. Often manual work is needed. Still, there is no single, suitable arrangement to handle both the process and expansion of a network. The objective of the invention is to alleviate the drawbacks of the known solutions. This is achieved in a way described in the claims.

US5903731 discloses a re-engineering method for standardizing data processing in a communication network while maintaining user services. Data channels between communicating network data processing components are made unnecessary by systematically providing bypass data paths. The data on each bypass, transparent to its terminating operational components, is routed through a network manager communicating in a standardized protocol. The manager thereby provides centralized control of data communications and provides standardized object oriented data representations and protocols.
the invention offers an arrangement and a method to form a communication network, as defined in the appended claims. It is convenient to think of a network as layers on top of one another, each layer representing a specific task area of the network.
the inventive arrangement is divided into several modules, such as a logical or physical topology of the network concerning a specific technology, where each one of them represents one layer of the network.
the necessary modules are used, i.e. the set of modules is chosen to form the network.
Certain network parts are formed in a relevant module.
Each module uses resources (capacities and routes for connections) from the module below, i.e. a module that represents the layer below, and provides recourses to the module above, i.e.
the inventive arrangement comprises several modules (each module representing a specific layer) for forming certain tasks of the communication network.
modules There are: conduit; line system; VC-4; 2Mbit/s; ATM link; ATM virtual path; ATM virtual circuit; IP; WDM; and cellular module, just to mention a few.
conduit line system
VC-4 2Mbit/s
ATM link ATM virtual path
ATM virtual circuit ATM virtual circuit
IP IP
WDM Wireless FDM
cellular module just to mention a few.
modules are going to be created when new technologies are taken into use. Which modules are used depends on the network to be formed.
the other guiding factor is the accuracy of the planning.
the more accurate the results are needed the more modules are needed.
Each module adds their own level of detail, so more modules are needed if the goal is network deployment, which requires the exact configuration setting for each piece of equipment and cross-connection.
a process of forming a network often takes into account different technical solutions. Therefore frequently the same upper level traffic and modules are used but the lower level modules can be changed when comparing different solutions. In this way it is possible to calculate the same network with e.g. SDH over fiber and with WDM implementation, and compare the costs of the solutions.
Each module comprises nodes and links between nodes, describing special node and link types of each layer.
a single node can be described as a base station in the cellular module, an access node in the transport module, and an "Ultrasite" (the product name) node in the detail module, for example.
Each module also comprises layer specific calculation and routing methods, such as calculating circuit switched traffic, or how routes are directed through different layers. Generally, the term routing describes choosing a data stream path (connection) between two endpoints. In this text routing also means a process to route the whole network or a specific network part, i.e. to route all data streams in a network or in a specific network part. Further, each layer and module comprises specific tasks, such as generation of cross-connections in the detail module.
FIG. 1 An example of a cellular network of 5 different layers is shown in Figure 1.
the conduit layer (1) carries the line systems (such as STM-4 or STM-16 equipment and routes), which are defined in the line system layer (2).
Every line system link (6) (such as 2 Mbit/s frames in radio link or STM containers) must have a conduit route (7) (a conduit may carry many line system links).
Every line system node (8) must be located at a conduit layer node (9).
Figures 2a and 2b show more detailed examples of conduit and line systems layers.
the numbers beside the conduits (21) tell the number of fibres in the conduits.
Figure 2b depicts equipment types in the sites and line systems used. 1*STM-16 takes 2 fibers in the representing conduit in the conduit layer.
the line system layer carries virtual containers (VC-4s), forming the SDH High-Order links (10) ( Figure 1) in the VC-4 layer (3). Every VC-4 link must have a line system link (6). Notice that one line system link can carry several VC-4 links. (Compare the situation in Figures 2a and 2b between the conduit and line systems layers.) Protected VC-4 routes require a primary and secondary line system route, i.e one VC-4 link requires two separate line system links. Respectively, the VC-4 layer carries VC-12 paths that are equal to 2Mbit/s paths from the granularity (frame size) viewpoint. In other words, VC-12s are created in the 2Mbit/s layer (4).
the logical connections are defined in the logical, connection layer (5), i.e. 8-64 kbit/s connections are carried by the 2Mbit/s layer.
the corresponding modules are conduit (conduit layer); line system (line system layer); VC-4 (VC-4 layer); 2Mbit/s (2Mbit/s layer); and cellular (logical connection layer) module.
Each layer uses resources (routing and capacity possibilities) from the layer below, and provides resources to the module above.
the main resource flow (11) (Figure 1) is from a layer to an adjacent layer only, intermediate layers are not bypassed.
the possibility to exclude intermediate layers allows an incremental forming process. It is possible to develop an initial network with just two basic layers (for example logical connections and line systems), and gradually redefine the network by adding more network layers. For example, the VC-4 layer can be created afterwards in the case of Figure 1.
the resource flow between modules is an automatic operation. It can be said that the flow forms an input from the module above to the module below.
the input to a module is the set of traffic requirements that need to be carried out by the module.
the capacity calculations of a module create new traffic demands to the underlying modules. Let's see the resource flow from the transmission link (connection) point of view. When the traffic has been routed to a transmission link it is possible to calculate the capacity of the transmission link. Typically the link is transported in the underlying layers. The link thus becomes a traffic demand to the underlying layer, and so on. Additionally the nodes of the other modules might create new nodes within modules (e.g. a BTS node in the cellular module creates a transmission node in the transport module).
Some of the key benefits of this arrangement is that the user can select which modules he wants to use and create all kinds of transport stacks. It is also possible to separate some traffic to one module and other traffic to another (e.g. 3G traffic to ATM modules, control traffic to IP module). It is also possible to combine traffic from different sources (convergence) to the same network. E.g. a common transport network can be used for traffic which arises from different sources.
a user selects a set of modules that is needed.
the set is totally user modifiable.
the user can:
FIG. 3 shows an example of how to combine different modules.
the cellular network is desired to comprise both the second and third generation subnetworks.
the cellular module can create logical connections (31,32) for both subnetworks.
the logical connections are carried by 2 Mbit/s PDH virtual links (33). These links are created in the 2 Mbit/s module.
the 2 Mbit/s PDH virtual links are carried by ATM virtual paths (34). These are created in the ATM virtual path module.
the ATM virtual paths are carried by high capacity PDH links (35) (created in the ATM link module). and the high capacity PDH links must be placed into physical conduits (36), which are fixed in the conduit module.
the logical connections are carried by ATM virtual circuits (37). These circuits are created in the ATM virtual circuit module. Respectively, the ATM virtual circuits are carried by ATM virtual paths (34). The ATM virtual paths are carried by high capacity PDH links (35), and the high capacity PDH links are placed into physical conduits (36). Another choice is to carry the third generation logical traffic in IP packets streams (28).
the IP packet streams are created in the IP module.
the IP packet streams can be carried in optical channels (39).
the optical channels are created in the WDM module. The optical channels must be placed into fibers and physical conduits (36).
conduit module creates both the second and third generation layers.
